GUSTAVE STEINKE, OF DENVER, COLORADO.

WRENCH.

Application filed February 28, 1912.

To all whomit may concern:

Be it known that I, Gusravn STEINKE, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in renches, of which the following is a specification.

The invention relates to a wrench and more particularly to the class of adjustable wrenches.

The primary object of the invention is the provision of a wrench in which an adjustable jaw is movable transversely thereof with respect to the stationary jaw and carries a rotatable thimble or cap provided with serrated and smooth surfaces whereby the jaws may securely grasp and hold an ordinary nut, pipe or other part, thus rendering the wrench useful for various purposes.

Another object of the invention is the provision of a wrench in which the handle thereof is pivotally connected so that the same may be angularly adjusted laterally or at right angles to its lateral movement and locked in such adjusted position, thereby enabling the wrench to be successfully worked or manipulated in contracted places.

A further object of the invention is the provision of a wrench in which the movable jaw and its handle may be independently adjustable for the convenience of the user and the movable jaw is provided with a turning cap so that the wrench may be employed as a pipe or nut wrench, the movable jaw and handle capable of being locked in adjusted position so as to obviate slipping thereof when the wrench is in use.

A still further object of the invention is the provision of a wrench which is simple in construction, thoroughly reliable and efiicient in operation and inexpensive in manufacture.

lYith these and other objects in view the invention consists in the construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, and brought out in the claim hereunto appended.

In the drawings :Figure 1 is a side elevation of a wrench constructed in accordance with the invention. Fig. 2 is a fragmentary, longitudinal sectional view through the wrench. Fig. 3 is an edge elevation. Fig. 1 is a sectional view on the line 44 of Fig. 1. Fig. 5 is a side view Specification of Letters Patent.

of a modified form of wrench. Fig. 6 is a fragmentary, longitudinal, sectional view thereof. Fig. 7 is an edge view thereof showing the handle in normal position in full lines and angular-1y adjusted in various positions in dotted lines. Fig. 8 is a fragmentary, sectional view on the line 88 of Fig. 5.

Similar reference characters indicate cor responding parts throughout the several views in the drawings.

Referring to the drawings by numerals the wrench comprises a stationary jaw 10 provided with a flat inner working face 11 and the major portion of this jaw is formed with a guide opening 12 through which is slidable the rack extension 13 of a movable jaw 14 provided with an outwardly tapering stud 15 formed with a reduced end 16 provided with an internally threaded bolt receiving socket 17 and upon this stud 15 is mounted a rotatable thimble or cap 18 provided with a flat working surface 19 and a serrated surface 20 both of which are adapted to cooperate with the surface 11 of the stationary jaw 10 for gripping the nut, pipe, or other part in the ordinary well-known manner, it being only necessary to rotate the cap or thimble 18 by bringing either of its surfaces 19 and 20 in the proper position with respect to the surface 11 of the stationary jaw. Passing through a suitable opening in the closed end of the cap or thimble 18 is a threaded screw 21, the same being engaged in the threaded socket 17 and serves torotatably fasten the said cap or thimble 18 upon the stud 15. The thimble 18 at its lower edge is formed with opposite notches 22 alternately engaged by means of a finger release spring-held locking dog 23 adapted to work in a suitable socket formed in the extension 13 near the outer end thereof, the locking dog 23 being designed to prevent the turning of the thimble 15 on the stud 18 when the thimble has been adjusted thereon.

Formed on the major portion of the stationary jaw 10 is a segment-shaped ratchet ear 24L provided with peripheral ratchet teeth 25 and swingingly connected to this ear is a handle 26, the same being connected to the ear by means of a pivot 27 and is provided with a slot 28 in which is mounted a sliding locking dog or pawl 29 for engagement with the ratchet teeth 25, the pawls being formed with finger engaging projections 30 which project through the slot 28 to opposite sides of the handle so that the said dog or pawl may be manipulated for releasing it from engagement with the ratchet teeth 25 on the ear 2% when desired, the said pawl or dog being normally held in engagement with the ratchet teeth 25 by means of a coiled expansion sprii'ig 31 surrounding same and acting thereon. Formed on the handle 26 or suitably mounted thereon is a stop lug 32, which latter limits the retracting movement of the dog or pawl 29 as will be clearly obvious. It will be evident that the handle 26 may be swung in an arc in one direction about the ear 2% but will be locked against reverse movement until the locking dog or pawl 29 is disengaged from the ratchet teeth 25, whence the said handle :26 may be shifted in the reverse di rection.

At one side of the ratchet ear 24L and formed on the major portion of the stationary jaw 10 are spaced bearings 33 in which is journaled a knurled spiral threaded adjusting screw 34: which meshes with the ratchet teeth formed on one edge of the ratchet extension 13 so that the movable aw may be adjusted to the desired degree with respect to the stationary jaw so as to accommodate and firmly grip a piece of work to be operated upon by the wrench.

In Figs. 5, 6, 7 and 8 there is shown a slight modification of wrench wherein the ratchet car 36 is swingingly connected to the major portion of the stationary jaw 10 for lateral movement in an arc, the said car being formed with an eye 37 loosely fitted between eyes 38 formed on the major portion of the stationary jaw 10 in spaced, parallel relation to each other, and through these eyes is extended the axle 39 of the adj usting screw it) to form a pivot for the said ratchet ear 36. One of said eyes 38 on the stationary jaw is provided with teeth 41 with which engages a spring-held pawl 42 mounted in the ratchet ear 36 so that the latter can be locked in various lateral, adjusted positions. Thus it will be seen that the handle can be adjusted in an arc in a lateral direction as well as in a direction at right angles to the lateral movement thereof, thereby enabling the wrench to be manipulated in contracted places.

It is thought that the construction and operation of the invention from the foregoing will be thoroughly comprehensive, and therefore, a more extended explanation is omitted.

What is claimed is In a wrench, a stationary jaw, a movable jaw' slidably connected with said stationary jaw, an outwardly tapered stud formed on said movable jaw, a thimble rotatably fixed to said stud and having opposed flat and serrated faces, and a latch member mounted within said movable jaw and engageable with the thimble at diametrically opposed points thereof for sustaining the same in ad justed position for holding either of said faces thereof opposite the working face of the stationary jaw.

In testimony whereof I affix my signature in presence of two witnesses.

GUSTAVE STEINKE.
